Title: Method and apparatus for transmission and reception of data
Inventor: BATARIERE MICKAEL D
IPC: H04L27/26
Filed: 2004-04-08
Abstract: To address the need for reducing pilot overhead, a method and apparatus for transmitting and receiving data is provided herein. A communication system having a transmitter (100) that utilizes adaptive modulation and coding (AMC) and utilizes lower-order modulated (e.g., QPSK) data as a substitute for pilot symbols during transmission. Data intended for a user utilizing a lower order modulation can be reliably detected, and if properly processed, used as pilots for a user that is trying to receive a higher order modulation (e.g., 64-QAM). Because lower order modulated data is utilized for pilots, fewer overall pilots are used. This greatly reduces pilot overhead, increasing data throughput.

Abstract: 본 발명은 미리 구리박(copper foil)에 어떠한 홀도 형성하지 않고 이산화탄소 가스 레이저의 에너지에 의해 고속으로 홀 벽에 관해 높은 신뢰성을 갖는 작은 직경의 관통홀(through hole)을 제조하는 방법과 이에 이용되는 보조재(auxiliary material)에 관한 것으로서, 그 제조방법은 금속 화합물 분말, 탄소분말 및 적어도 900℃의 융점과 적어도 300KJ/mol의 결합에너지를 갖는 금속분말로 이루어지는 그룹으로부터 선택된 적어도 하나의 분말을 3 내지 97부피% 함유하는 유기물(organic substance)의 코팅(coating)이나 시트(sheet)가 이산화탄소 가스 레이저로 조사될 적어도 하나의 구리박 표면상에 형성되거나 배열되고, 그리고 상기 투과홀을 형성하기 위해 필요한 펄스(pulse)의 이산화탄소 가스 레이저로 그 표면을 조사함을 포함하여 구성되며; 또한, 이산화탄소 가스 레이저로 구리적층판(copper-clad laminate)에 투과홀이 제조될 때 사용되는 보조재는 금속화합물 분말, 탄소분말과 적어도 900℃의 융점 및 적어도 300KJ/mol의 결합에너지를 갖는 금속분말로 이루어지는 그룹중에서 선택된 적어도 하나의 분말이 3 내지 97부피% 함유되는 유기물의 코팅 또는 시트임을 특징으로 한다.
